Summary: This article proposes a novel nonlinear uncertainty estimator-based time-varying sliding mode control (SMC) scheme for servo systems with prescribed performance. The scheme uses a nonlinear uncertainty estimator to handle unknown nonlinearities and a robust integral of the sign of the error (RISE) feedback to handle estimation errors and uncertainties. A modified prescribed performance function (PPF) is incorporated into the control design to restrict tracking errors within predefined boundaries, and a time-varying sliding mode (TVSM) controller is developed to improve control performance. The validity and feasibility of the proposed scheme are verified through simulations and experiments based on a motor driving system.

Summary: In this article, an improved delayed output-feedback sliding mode control method is proposed for a fuzzy system with arbitrary order. A new time-delay estimator is designed to approximate the output derivatives on the sliding surface, which has good noise attenuation capability. The estimator and controller parameters are co-designed by genetic algorithm, considering tradeoffs between closed-loop stability, noise attenuation, and estimation accuracy.

Summary: The concept of phase deficit for systems with homogeneous higher order sliding mode (HOSM) controllers is discussed in the literature. Necessary conditions for finite-time convergence are derived based on the phase deficit, and several homogeneous control algorithms of different orders are analyzed. It is found that a positive phase deficit indicates finite time convergence, but under certain controller parameters, asymptotic conversion or nonvanishing oscillations may occur. The necessary conditions for finite-time convergence, infinite-time convergence, and finite-frequency oscillations are obtained through the developed approach.

Summary: A numerical model was developed to analyze lightning attachment on UHV-AC double-circuit transmission lines. Simulation results showed that upward leaders simultaneously occurred on the ground wire and the upper-phase conductor when the phase conductors were energized. A new expression for calculating the striking distance on the ground wire was proposed based on the simulation results. Additionally, high voltage, phase angle, and terrain slope were found to increase the surface electric field of the upper-phase conductor.
